,Application March 6, V1933, Serial No. 659,732

This .invention relates `to devices for closing 'the mouth orifices oi yreceptacles adapted to contain liquids, plastic materials, powders and the like, in a manner to permit of ready accessibility, as for instance the type known as collapsible tubes.

Such tubes are usually cylindrical, their lower ends being flattened after lling, folded upon themselves to form impervious joints, which upon further folding causes the contents to be extruded through the nozzles at their upper ends in such quantities as may be desired.

rlhe nozzle or discharge element is set securely in the opposite end of the tube in a manner to prevent leakage and is provided with a reduced, outwardly extending stem, usually screw-threaded and having an axial passage, circular or polygonalin cross section.

To close the passage through the stem a screw cap is generally employed, with or without a gasket, to be turned by hand in applying and removing, which operations are diicult to accomplish, particuarly if the cap adheres, or the threads become crossed; furthermore, the cap, being a separable element, is readily lost.

The invention is by no means limited in use to such tubes, but may be employed in connection with other types of containers, of widely variant nature, such as storage battery cells, etc,

It is therefore an object to provide a closure nonseparable from the container, hence not liable to loss.

A further feature is in the provision of a closure easy to operate, not dependent upon screwthreads, including the necessity of using the fingers as a wrench, and, due to the resiliency of its contacting members, maintain a tight joint when the cap is closed.

Another purpose is to produce a form of closure which may be transferred from one container to another having a corresponding stem.

These important objects are accompished by the novel design, construction and combination of parts hereinafter described and illustrated in the accompanying drawing, constituting a material component of this disclosure, and in which:-

'Figure 10 is a perspective view showing the 'upper portion `of a conventional storage battery cell on which closures of the type described are provided.

, i) Throughout the several views shown in Figures 7 1 to 9 inclusive, the numeral 15 designates in Igeneral the body of a collapsible metallic tube, such as is used for holding all manner of plastic, soft and semi-liquid substances.

United integrally to the interior of the tube, '75

at its upper end, is an annular flange 16, its upper edge merging into a convex cover 17, usually shaped as the frustum of a cone and terminatv ing in a stem 18, ordinarily screw threaded exteriorly to receive a corresponding cap, this stem having an axial passage 19, and constituting a nozzle.

In the present invention the cap is substituted by an internally threaded collar 20 tight fitted 85 and of such length that its upper edge is approximately level with the end of the stem 18.

Extending radially Afrom the collar 20 is a lug 21 having pintles 22 on both of its sides, and at a point directly opposite the lug 21 is a detent ,o

catch 23.

A cap comprising a crown plate 24 having an annular skirt 25 adapted to freely engage over the upper, slightly conical portion of the collar 20, is provided with a pair of plate-like projections 26,' spaced to closely receive between them the sleeve lug 21, to which they conform in prole.

Formed in the adjacent inner sides of the projections 26 are grooves 27, open at the top or 1 posite the hinge device, is adapted to engage the detent catch 23 on the collar 20 when the cap is forced into seating position.

- the lug 21', having the pintles 22', is formed integrally with the stem and cover, thus reducing the number of parts and materially augmenting the strength and simplicity of the device.

Figure 9 shows a modification in which the lug 21 is provided with pintles 33 having beveled' faces converging downwardly in the manner of a wedge, and in the cap extensions 26' the grooves are omitted, but the openings 28 are circular and of a depth to receive the pintles as shown.

It is to be understood that the material of which the parts are made is suillciently resilient to permit the lugs 2,6 to spring slightly apart 'in entering the pintles into the socket openings, and also 'to allow springing of the skirt 25 when the node 29 is snapped past the detent 23.

In Figure 10 is shown a storage battery composed of a series of cells which require filling,

,the cells being supplied with nozzles having closures of the type previously described, two being shown closed and one in an open position. Other adaptations will readily suggest themselves.

From the foregoing it will be seen that a simple device for this purpose has been disclosed in thepreferred form of its embodiment, but it is not desired to restrict the details to the exact construction shown, it being obvious that changes, not involving the exercise of invention, may be made without conflicting with the scope of the appended claims.

Having -thus described the invention, what is claimed as new and desired to secure by Letters Patent, 1s:

1. A closure comprising in combination, acontainer having a nozzle, a lateral lug on said nozzle having two alined oppositely extending pintles, a cap having a skirt portion to embrace said nozzle, paired projections on said cap to receive said lug, said projections having portions level with the top of said cap, seats in the proximate sides of said projections to receive said pintles, and grooves leading from the level portions of said projections to said seats, said grooves being of slightly lesser width than the diameter of said pintles to permit forced passage.

2. A closure comprising in combination, acontainer having a neck terminating'in a mouth, a flat lug extending radially from said neck, a

pintle on each side of said lug, a cap, projections on said cap to receive said lug therebetween, re-

.tate manipulation of said cesses in the proximate faces of said projections, said pintles being entered by pressure thru grooves in said projections extending from the tops thereof, and means on said cap by which it may be manipulated.

3. A closure comprising in combination, a container having a screw threaded stem, a collar tight fitted thereon, said collar having a conical upper portion, a plate lug extending radially from said collar, pintles on said lug, a cap having crown and skirt portions to rest upon and overlie said collar, projections on said cap to engage said lug between them, recesses in the proximate faces of said projections to receive said pintles, means for entering the pintles therein from the crown side of `said cap, and a cushion plate carried by the under side of said cap to close the opening in said stem.

4. A closure comprising in combination, a container having a screw threaded stem, a collar tight tted thereon, said collar having a conical upper portion, a plate lug extending radially from said collar, pintles on said lug, a cap having crown and skirt portions to rest upon and overlie said collar, projections on said cap to engage said lugbetween them, recesses in the proximate faces of said projections to receive said pintles, means for entering the pintles therein from the crown side of said cap, a detent catch on said collar opposite said lug, and an inreaching node in the skirt of said cap to engage said detent catch upon closing the cap.

A closure comprising in combination, a container having a nozzle, a lateral lug on said nozzle having two aliried ODDOSitely extending pintles, said pintles having beveled faces converging downwardly, a cap having crown and skirt portions, a pair of plate projections on said cap to straddle said lug, said projections having circular recesses in their proximate faces to retain said pintles when forced therein, and means to resiliently retain said cap when in operative position.

6. In a hinged closure for containers, a supporting collar associated with the nozzle of the container, a radial outstanding lug on said collar, opposed outstanding pintles integral with the parallelfaces of said lug, a cap having crown and skirt elements respectively to extend over and to surround said collar, a pair of projections on said cap to engage the sides of said lug, slots having bottoms in the inner faces of said projections to rotatably receive said pintles, means in the bottoms of said slots to prevent retraction.
